SURFACE-WATER-DRAINAGE CONNECTION.

SPECIFICATION forming part of Letters Patent No. 428,342, dated May 20,1890.

Application filed March 4, 1890. Serial No. 342,604. (No model.)

To aZZ whom t may con/cern,.-

Be it known that I, CHARLES P. K. KAHLER, resid-in g in the city ofBaltimore and State of Maryland, have invented certain new and usefulImprovements in Surface Tater- Drainage Connections, of which thefollowing is a specification.

My invention has for its object to provide suitable means whereby thewaste water of the surface-drainage system may be connected in such amanner as to avoid the necessity of providing gutter-ways atstreetcrossings, and also to provide means whereby the water may becarried from one side of the street under cable-conduits and the like tothe opposite side.

To this end my invention consists in providing a suitably-arranged pipeor conduit, which is bent under the transverse road-bed to apoint belowthe cable-conduit, (when used on a street provided with a cable-line,)one end of which opens from an inlet and basin arranged at t-he higherside of the said transverse roadway, so that the surface-water runningdown the main street into said inlet and basin will enter the said pipeor conduit at one end and be again discharged into the gutter at itsopposite end.

It further consists in arranging with said pipe or conduit lateralconnections, whereby the waste water of the cross-street will also entersaid pipe or conduit and be conveyed into the gutter of the otherstreet, and con'- necting with the said water or gutter connection pipeor conduit suitably arranged branch pipes with valves adapted to beoperated from the street-surface, whereby water under greatpressure maybe inj ected into the gutter connection pipe or conduit to clean andemptythe water and sediment from it when required.

Finally, my invention consists in the sundry novel arrangment andcombination of parts all of which will hereinafter be fully described inthe annexed specification, and particularly pointed out in the' claims,reference being had to the accompanying drawings, in which- Figure l isa longitudinal section of my improvements, taken on line l l, Fig'. 2,showing the same in an operative condition, and Fig. 2 is a plan viewthereof.

In the accompanying drawings, A indicates what I will term a mainroadway or street, and B a street which crosses the main street at rightangles, and which, for example, I show provided with acable-conduit fortractionroads. o

The main street A, which is adapted for surface-drainage in thedirection indicated by the arrow marked l, is provided with the usualgutter or water way ct a', which is interrupted at the intersection ofthe two streets A and B, the section a of the gutterway ending at aninlet-basin C, formed with the closed sides and ends c c', while thesection ct of the gutter begins at an outlet and hood D, as most clearlyshown in Fig. 2 of the drawings.

E indicates an underground connection between the twogutter-sectionsact, Which consists of a pipe bowed or bent down to passunder the conduit C or other obstruction, the deepest portion of saidpipe being at a point beyond the center of the cross-street B, towardthe discharge end thereof, said end being formed with a direct incline,as shown at E2. By reference to Fig. l of the drawings it will be seenthat the waste water will enter the end e of the pipe E and soon `lillup the said pipe, and in reachingits level will discharge at its end einto the gutter-section a.

To form a convenient means for quickly and effectually cleaning the pipeor conduit E of any deposits which might collect in the bottom of saidpipe and to empty theWater therefrom, I provide said pipe With openingsG, having contracted inner ends, g, which open into said pipe centrallythereof flush with the bottom, and into which project the ends of shortbranch pipes H, connected with a pipe-section I, connected at one end towater-main J and closed at its opposite end,

as at j. Cut-olf valves are disposed in each of the branches H, whichare arranged to be operated from the street-surface in any wellknownmanner. By this construction it will IOO the direction of its dischargeand thoroughly and quickly wash therefrom and force out into the gutterd any sedimentary or foul deposits which may have lodged in said pipe,as well as the wat-er contained therein.

M denotes aman-hole, which connects with the pipe near its lowest point,whereby the condition of the pipe may be observed or access theretoobtained.

N denotes outlets or basins located at the intersection of the street Bwith the street A, which are connected bymeans of short pipes 0 O withthe pipe or conduit E, as shown, whereby the water from street B, incase the drain thereof is in the direction of street A, will bedischarged through the pipes O and conduit E into the glitter d.

While my invention is especially adapted f for use in connection withstreets having cable-conduits, it is manifest that the same is readilyadapted for the more general use of dispensing with the obnoxiousgutter-ways located at street-crossings. It also affords a simple meansfor carrying the water of an unpaved or roughly-paved street under asmoothly paved street such as asphalt blocks, &c.-so as to allow ofconstructing such smooth street with a continuous smooth surface at thestreet-crossings.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. In a natural drainage system, the combination, with a surface gutterformed in sections, inlets and outlets located at the ends of suchsections, having the sides and one end closed, of an underground pipe orconduit opening at its ends into said inlets and outlets, whereby acontinuous gutterway is formed, substantially as and for the purposedescribed.

2. In a natural drainage system, the combination, with a surface gutterterminating at street-crossings, ot an underground pipe or conduitconnecting the gutter on opposite sides of the crossing street, saidpipe or conduit formed with openings in its lower face, valved pipesconnected with said openings, and with a pipe containing water underpressure, whereby the said conduit-pipe may be automatically cleaned andemptied, substantially as and for the purpose described.

3. In a natural drainage system, the combination, with thegutter-sections a a', the inlets and outlets C D, located at the ends ofsaid sections, ot' the underground conduit or pipe connectingsaidgutter-sections, said pipe formed with a bent portion, the lowestportion of which is nearer the discharge than the receiving end of suchpipe, and a manhole connected with such lowest portion, substantially asand for the purpose described.

4. In a natural drainage system, the combination, with a surface gutterformed in sections terminating at the street-crossings, and inlets andoutlets formed at the ends of each gutter-section, of an undergroundconduit or pipe E, connecting the gutter on opposite sides of thestreet, said pipe formed of a downwardly-bent portion extended for morethan half its length, and an upwardly-inclined portion, and cleaning andemptying pipes projected within the lower face of said pipe or conduitin the direction of its discharge, and means for forcing water underpressure into said cleaning and emptying pipes, substantially as and forthe purpose described.

5. In a natural drainage'system, the combination, with a surface gutterformed in sections terminating at the street-crossings, inlets andoutlets formed at the ends of said sections to receive the water, and anunderground conduit or pipe E, opening at its ends into said inlets andoutlets, whereby a continuous gutterway is formed, of the naturalgutters of the crossing street formed with inlets and outlets N at thejuncture of the streets, and the lateral branch pipes O, opening at oneend into said basins and at the other end into the conduit or pipe E,whereby the water of the cross-street is carried oit into the gutter-wayof the main street, substantially as and 'for the purpose described.

6. In a natural drainage system,the combination, with a surface gutterformed ot sections terminating at street-crossings, and inlets andoutlets CD, provided at each end of such gutter-sections, of anunderground conduit or pipeE, opening at its ends into the adjacentinlets and outlets, said pipe or conduit formed 'with openings in itslower wall, said openings contracted in the direction of the dischargeend of said pipe, a series of branch pipes II, projected at one end intosaid openings, provided with valves adapted to be operated from thestreet-surface, a main or pipe adapted to hold water under pressure, anda supplemental pipe I, connected at one end to said main, its oppositeen d closed, said supplemental pipe connected with t-he branch pipes,all arranged substantially as and for the purpose described.
